Answer 2

By substitution method

9.2x+0.3y=1.3 ---(1)

0.4x+0.5y=2.3---(2)

from the equation (1),we get

y=1.3-0.2x/0.3 --(3)

Putting the value of y in equation (2) we get

0.4x + 0.5(1.3-0.2x)/0.3 =2.3

0.12x+0.65-0.10x=0.69

0.02x=0.04

x=2

Putting the value of x in equation (3), we get

y= 1.3-0.2(2)/0.3=0.9/0.3=3

Hence , x= 2 and y = 3.
